Hello, According to a guy name bo polny who has been forecasting the change in the price of bitcoin using the cycle analysis. He stated it on his last video on May 10th, 2019 that the price of bitcoin will go down in May, but it will recover on mid-june 2019.
I link the video 
I honestly been watching his updates for a while, and he has clearly forecast the bitcoin trends, so this is the first time I will take action.
This is not advice to anyone, but this is what I personally do taking my own risk. I will not buy bitcoin now, I will wait up to June, I think the price will go down eventually in May. Obviously, this is not based on any fact, but bo polny advice and following the cycle trend. Then on June buy BTC and wait for another 10% up on a weekly average.
